I have male cats spraying all around my house and this morning I went to take clothes out of the dryer and Pee-yeww!! They have sprayed right near my dryer vent and the smell is getting in my dryer. Any safe tricks to keeping them away? I would spray them back with a spray bottle if I could catch them but I need something that will keep them away. I do have a female cat inside but she is fixed. There is not a dryer sheet in the world that will cover that smell on our clothes so I need to do something.
